This much valued urea-formaldehyde/acid hardener glue has been used for many years in boat building and light aircraft wood applications for its strength and dependability of bond. The powder resin is mixed with warm water into a thin brushable cream and the hardener is applied to the mating surface. The two parts are then clamped in close contact for the set to be completed. Working or open time depends on the ambient temperature and humidity but will be in the region of 5-25 minutes. Similarly the clamping time will be influenced by these factors but will need to be left for 1.1/2 - 3.1/2 hours. However, full strength may take up to 14 days to acquire.

Suitable for scorchingObviously, this adhesive has it's place in boat building and light aircraft construction. However, seeing as I found no information on the internet regarding adhesives for scorched pieces, I figured this would be a good place to confirm it is strong enough to deal with heat. I used it to bond 1.5mm constructional Oak veneer to MDF as well as solid wood lipping, and even after two passes with a blowtorch I had no bubbles or warping occur. I would highly recommend this product for scorching.
